Original Equipment Manufacturer Serving Pressure Parts Needs for Over One Century

FABRICATED PRODUCTS

Superheaters

Superheater materials, configuration, and design vary significantly. Some of these materials may require heat treatment to ensure prolonged life. BTA can assist with up-grading your superheater components. Superheaters often have tight radius bends. BTA has specific hot-forming procedures to assure acceptable bend geometry and material mechanical characteristics.

Headers

BTA can supply you with all your replacement header needs: machined, welded, tested, and stress relieved, if required. During the fabrication process, the pressure parts produced are under the strictest surveillance of BTA’s Quality Control Department to ensure compliance with the ASME codes.

Waterwalls

Waterwall materials, configuration, and design vary greatly depending on the style of boiler. Most waterwalls utilize a membrane panel construction. BTA uses a fully automatic, submerged arc process to weld both sides of the panel.Bent panels are typically fabricated on a panel bender to assure correct alignment of tubes.

Economizers

With extensive experience, the latest technology, surface materials and configurations, BTA has complete economizer design capabilities. We begin with the optimum surface for the application. We consult with you on your type of fuel, heat source, flue gas characteristics, operating hours, load variation, available draft, fouling, pluggage, sootblower requirements, gas velocity, and temperatures to provide you  with the optimum solution.

WELD OVERLAY

Boiler Tube Company of America is a leader in providing boiler replacement pressure part components that improve unit performance by extending component life. Primary to achieving extended life is the use of Boiler Tube Company of America’s spiral clad tubing that utilizes state-of-the-art welding technology. Boiler Tube Company of America has developed a Hot Wire Gas Tungsten Arc welding process using Wave Pulse Technology (patented). Use of the Wave Pulse Technology with automatic hot wire TIG utilizing a fully integrated robotic microprocessor controlled system results in reduced weld metal dilution chemistry throughout the thickness of the overlay and favorable fusion properties.

IMPROVE EFFICIENCY, OPERATION AND CONSUMPTION WITH THE GOAL OF REDUCING OPERATION & MAINTENANCE SPENDING

MIXERS TO IMPROVE PERFORMANCE

SCR Upgrades

It is as important to establish good distribution of flue gas flow, temperature, particulate, and NOx upstream of the ammonia injection system as it is to maintain ammonia distribution to the SCR. Optimizing distribution:

  • Reduces effects of unit firing & flow configurations
  • Provides homogenous flue gas and particulate mixing at the catalyst face
  • Maintains mixing at low load operation
  • Reduces the catalyst minimum operating temperature
  • Reduces number of NOx monitors
  • Reduces ABS formation
  • Improves air heater efficiency

DSI Upgrades

Coupling sorbent injection with Babcock Power mixing technology ensures full mixing in short section of ductwork across the operating load range improving removal and reducing sorbent consumption. BPE Delta DSI systems reduce the number of lances required by more than 50% compared to a traditional DSI system. Locating the DSI system upstream of the SCR provides additional benefits including:

  • Reducing catalyst minimum operating temperature
  • Increasing sorbent residence time and therefore reducing lime consumption
  • Reducing ABS scaling
  • Improving air heater efficiency
  • Reducing ammonia slip
  • Increasing catalyst life
  • Removing a fraction of HCl upstream of the WFGD system

EXPERTLY ENGINEERED DOOR SOLUTIONS FOR MAXIMUM SAFETY AND COST SAVINGS.

IMTEC FLEXISEAL ACCESS DOORS

Boiler Tube Company of America/Imtec has been manufacturing Access Doors for the power industry since 1984. We have over 20,000 units installed and have experience in all areas of the power plant from the boiler to the stack.

 The FLEXISEAL doors have one or more yokes with closing screws that act on center point(s) of the door. This flexes the door plate toward the interior and assures a tight seal with the gasket. When opening the door, special safety features in the latch and screw mechanism(s) will assure that the latch pin cannot be removed easily until the door plate with its gasket is safely retracted from the sealing surface on the frame plate, thereby revealing any dangerous internal pressure and also preventing damage to the gasket.

IMTEC BOILER DOOR WITH TUBE PANEL

Imtec’s boiler doors with matching tube panels are available with a max operating temperature of 2800 degrees. The boiler door must withstand high operating and excursion gas temperatures. Therefore, on boiler doors type BC the inner side of the door plate is equipped with high efficiency insulation supported by interior shelves and all contained in a protective Insulation pan which is protected by a 2” layer of castable refractory. For flexibility and heat expandability the pan is made with slots and in movable sections from heat resistant steel. When installed, this insulation pan must be closely surrounded by water wall tubes shaped in a fashion to match the conical shape of the insulation pan.

IMTEC CATALYST MODULE REMOVAL DOOR (LAYDOWN TYPE)

Imtec Catalyst doors are designed to minimize the time required to remove and reinstall your Catalyst Modules. In most cases we can reduce the time needed to remove and reinstall casing/doors by 75% thus resulting in a very short payback period.

We have over 500 numerous installations of our doors in various plants throughout the U.S. A reference list is available upon request.

IMTEC CATALYST MODULE REMOVAL DOOR (SWING TYPE)

Imtec Catalyst doors are designed to minimize the time required to remove and reinstall your Catalyst Modules. In most cases we can reduce the time needed to remove and reinstall casing/doors by 75% thus resulting in a very short payback period. We offer doors that will work regardless of the type of removal you are performing (tracks, monorail or carts). Our patented door also allows for it to be raised above the floor level to swing out of the way.

We have over 500 installations of our doors in various plants throughout the U.S. A reference list is available upon request.

IMTEC DUCT DOORS (SINGLE & DOUBLE)

Imtec’s duct doors are available in three different styles: uninsulated, insulated and double doors with various operating temperatures from 400 degrees to 1000 degrees.

IMTEC INSULATED SINGLE DOOR WITHOUT TUBE PANEL (MAX OPERATING 1800)

Imtec’s boiler doors without tube panels are available with a max operating temperature of 1800 degrees. The boiler door must withstand high operating and excursion gas temperatures. Therefore, on boiler doors type BM the inner side of the door plate is equipped with high efficiency insulation supported by interior shelves and all contained in a protective insulation pan which, for flexibility and heat expandability, is made with slots and in movable sections from heat resistant steel. When installed, this insulation pan must be closely surrounded by either refractory, a steel casing or water wall tubes shaped in a fashion to match the conical shape of the insulation pan.

IMTEC PENTHOUSE DOOR

Imtec’s penthouse doors are available in three standard sizes. With operating temperatures of 1000 degrees, these large penthouse doors permit quick access and rapid cooling of the boiler penthouse at forced outages.

IMTEC ROOF DOOR

Imtec’s roof doors are available in two different styles, with operating temperatures from 400 degrees to 1000 degrees.
